3 Terms and definitions
The terms and definitions defined in GB/T 6974.1 apply to this document.
4 Basic requirements
The driver's cab and control station of bridge and portal cranes shall comply with GB/T 20303.1.
5 Driver's cab structure
5.1 The dimensions of the driver's cab specified in Figure 1 are minimum values, and it is advisable to take larger values when practical. Through the seat calibration point (SIP), the net height of the driver's room should not be less than 1 600 mm, the net width should not be less than 900 mm, and the net depth should not be less than 1 300 mm.
5.2 The total internal volume of the driver's compartment shall not be less than 3 m'. In determining the volume and dimensions, the number of staff allowed in the driver's compartment and the actual working hours shall be taken into account.
5.3 The structure of the driver's cab shall have sufficient strength and rigidity and shall be safely and securely connected to the crane. The structure and its connection ends shall be sufficient to withstand the working loads generated by personnel, electrical control equipment, auxiliary facilities and during maintenance, as well as the dynamic loads generated by the crane during operation, etc.
6 Driver's seat
Considering the actual working conditions, the seat should meet the following requirements:
a) Stable and adjustable in the range of 3° to 7° of recline;
b) easy to adjust to a comfortable seating position with a range of 80 mm from the middle position in the horizontal direction (forward and backward) and 50 mm from the middle position in the vertical direction;
c) The backrest is equipped with a sloping backrest, which is shaped to comfortably support the back;
d) The surface material is breathable;
e) Equipped with damping springs and vibration damping devices;
f) to provide a comfortable working position for the driver, it should be able to be locked in both horizontal and vertical directions;
g) Suitable cushions and adjustable armrests;
h) The seat is constructed to facilitate access.
To provide the driver with a more comfortable operating angle and a more reasonable range of visibility, a swivel base can be provided on request.
7 Control elements
7.1 The form and characteristics of the arrangement of the control elements shall comply with the provisions of GB/T24817.1.
7.2 Special requirements for bridge and portal cranes shall comply with the provisions of GB/T24817.5.
8 Safety protection
8.1 The driver's room is configured in the metallurgical crane, should be subject to high temperature radiation heat insulation measures in the part.
8.2 driver's room configuration in a corrosive environment when the use of bridge and portal cranes, should be taken to prevent corrosion affecting the strength of the metal structure of the driver's room, as well as measures to prevent corrosion of the glass and affect the driver's line of sight.
8.3 Measures shall be taken to prevent the glass of the driver's cab from falling outwards as a whole.
9 Appearance quality
9.1 The shape of the driver's cab and the colour of the paint should be coordinated with the colour of the crane, the paint should be bright, complete, colour - consistent, there should be no roughness, wrong paint, paint leakage, wrinkles, pinholes and serious hanging and other defects.
9.2 The adhesion of the paint film on the metal surface of the driver's compartment shall conform to the quality requirements of Grade 1 in GB/T9286-1998.
